[TenTec] Kinda OT

[Mike Hyder -N4NT-]

Couldn't find my slipstick but cipherin' it on paper gave the following 
values:

Current for full dissipation (50 w) = 18.26 Amps

Voltage drop @ 18.26 Amps across 0.150 Ohms = 2.74 Volts

This causes me to wonder if a properly rated fuse wouldn't work as well --  
perhaps a 15 Amp 3AG fuse?
